Quick Answer
Scar revision and keloid treatment are among the most nuanced areas of plastic surgery because no scar can be erased — it can only be improved. The goal of treatment is to reduce the scar's visibility, improve its texture and contour, and in the case of keloids, stop the abnormal growth and prevent recurrence. For Indian patients specifically, the risk of hypertrophic scarring and keloid formation is significantly higher than in lighter-skinned populations — genetic predisposition, skin tension, and wound depth all contribute. The most important principle in managing scars and keloids in Indian patients is matching the treatment aggressiveness to the scar type, treating early rather than waiting, and having realistic expectations about what improvement means — because a revised scar is still a scar.
Why Indian Skin Scars Differently
Fitzpatrick skin types IV–VI — which encompasses most of the Indian population — carry a significantly elevated risk of abnormal scarring compared to lighter skin types. The reasons are biological:
Fibroblast activity in darker skin is more reactive. When tissue is injured, fibroblasts migrate to the wound and produce collagen to repair it. In patients with darker skin, fibroblasts are more proliferative and produce collagen for longer after the wound is closed — leading to scars that are thicker, raised, and more pigmented than in lighter-skinned patients with equivalent injuries.
Melanocyte response is more exuberant. Any inflammation or injury in Indian skin triggers increased melanin production in the surrounding and scarring tissue — producing post-inflammatory hyperpigmentation (PIH) that makes scars darker than the surrounding skin. This PIH can persist for months to years even after the scar itself has matured.
These characteristics do not mean that Indian patients cannot achieve good scar outcomes — they mean that scar management must start earlier, be more aggressive, and involve specific strategies (sun avoidance, silicone, pigmentation treatment) that address the distinctive healing response.
Types of Scars: Defining the Problem Before Choosing the Solution
Treatment selection depends entirely on scar type. Treating a keloid like a hypertrophic scar (or vice versa) produces poor results. The key distinction:
Normal Mature Scar (Normotrophic)
A scar that has healed normally — flat, pale at maturity, confined to the original wound boundary. No treatment is required beyond time and protection. Normal scars take 12–18 months to fully mature; patients who present requesting revision of a normal scar at 3 months are often presenting a scar that would have become excellent without intervention.
Hypertrophic Scar
A raised, often itchy, red scar that remains within the boundaries of the original wound. It forms due to excessive collagen deposition during healing. The critical feature distinguishing hypertrophic scars from keloids is that hypertrophic scars respect the wound boundary and often improve spontaneously over 12–18 months, though this can be accelerated with treatment. They are more common at sites of high skin tension (shoulders, sternum, upper back, joints) and are associated with wound infections, prolonged healing, and certain anatomical sites.
Keloid
A keloid is fundamentally different from a hypertrophic scar: it grows beyond the original wound boundary, invading normal surrounding skin. It does not spontaneously improve and typically continues to grow. Keloids are more common in patients of African and South Asian descent, with a strong genetic component. They most commonly affect the earlobes, chest (especially the sternum), shoulders, upper back, and jaw area. A key diagnostic feature is that the patient usually has a history of keloid formation in prior scars — confirming the genetic tendency.
Keloids are the most challenging scar variant to treat because they have a high recurrence rate after any single treatment modality. Combination approaches (intralesional injections plus compression plus silicone) reduce recurrence rates; surgical excision alone typically leads to regrowth. At Inform Clinic, keloid treatment protocols are individualised and multi-modal.
Atrophic Scar
A sunken, pitted scar resulting from insufficient collagen production — more tissue was lost than was replaced. Acne scars are the most common example. These are the opposite problem of keloids — too little collagen rather than too much. Treatment involves procedures that stimulate collagen production (microneedling, subcision, laser resurfacing) to fill and elevate the depressed scar to the level of the surrounding skin.
Contracture Scar
A scar that tightens across a joint or mobile area, restricting movement. Most commonly results from burns. Treatment is reconstructive — releasing the contracture with Z-plasty, W-plasty, or skin grafting to restore mobility. This is the domain of reconstructive plastic surgery and is assessed individually.
Non-Surgical Treatments for Raised Scars and Keloids
Silicone Gel and Sheeting
Silicone is the most evidence-backed non-surgical intervention for hypertrophic scars and keloids. Applied as a gel, spray, or adhesive sheet over the scar, silicone works by maintaining hydration in the stratum corneum — reducing the water vapour loss that activates fibroblasts. It also regulates cytokine activity and reduces capillary activity in the scar, leading to flattening and fading.
Key facts about silicone therapy:
- Must be used consistently — minimum 12 hours per day, ideally 23 hours per day
- Requires 3–6 months of use to show meaningful improvement
- More effective on early, active scars than on mature (>2 years old) scars
- Completely safe — no systemic absorption, safe in pregnancy, safe on children
- Under-used because patients stop using it within weeks — compliance is the critical failure mode
For post-surgical scars at Inform Clinic, silicone gel application is standard from the point of wound closure (day 14–21 post-operatively) and continued for a minimum of 3 months.
Intralesional Steroid Injection (Triamcinolone Acetonide)
The most widely used pharmacological treatment for hypertrophic scars and keloids. Triamcinolone acetonide (TAC) injected directly into the scar reduces collagen synthesis, suppresses fibroblast proliferation, and reduces the inflammatory cytokines maintaining scar activity. It produces measurable flattening and softening in responsive scars.
Protocol: injections at 4–6 week intervals, typically 3–5 sessions for hypertrophic scars, and 5–10+ sessions for keloids.
Side effects of intralesional steroids:
- Skin atrophy (thinning) — can cause a depression or transparent skin overlying the treated area. More likely with high concentrations or injections that are too superficial
- Hypopigmentation — whitening of the treated skin, which can be permanent in darker skin. TAC-induced hypopigmentation is particularly problematic in Indian patients with high skin contrast and must be discussed before treatment
- Telangiectasia — small visible vessels in the scar area
These side effects are concentration-dependent. Using the lowest effective concentration — rather than high-dose injections — reduces risk while maintaining efficacy. 5–10mg/ml is typically appropriate for early hypertrophic scars; 20–40mg/ml may be used for established keloids with careful monitoring.
For keloids, steroid injection alone has a significant recurrence rate (50–70%). Combining steroid injection with other modalities (pressure therapy, silicone, laser) dramatically improves long-term outcomes.
Pressure Therapy
Sustained pressure over a scar or keloid reduces collagen production by causing local tissue hypoxia. Compression earrings after earlobe keloid excision and compression garments over larger body keloids are standard components of keloid management protocols. Pressure must be maintained at 20–30mmHg for at least 12 hours per day for a minimum of 6 months to be effective.
For earlobe keloids specifically — the most common keloid site in Indian patients — a combination of surgical excision followed by immediate post-operative steroid injection and compression earring for 6 months has significantly lower recurrence rates than excision alone.
5-Fluorouracil (5-FU) Intralesional Injection
5-FU is an antimetabolite that inhibits fibroblast proliferation and collagen synthesis. It is used as an alternative or adjunct to steroid injection in keloids, particularly when steroid-related side effects (hypopigmentation, atrophy) are a concern. 5-FU causes less pigmentation change than TAC and can be used in combination with TAC to allow lower steroid doses.
Typical protocol: 5-FU 50mg/ml injected intralesionally at weekly or biweekly intervals, 5–10 sessions. Combined TAC/5-FU protocols show better outcomes than either alone in several clinical trials.
Laser Treatment for Scars
Multiple laser modalities are used for scars, addressing different aspects:
Pulsed Dye Laser (PDL) — targets the vascular component of active scars, reducing the redness and vascularity that drives continued collagen production. Most effective on early red, vascular hypertrophic scars. Typically 3–5 sessions at 4–6 week intervals.
Fractional Ablative CO2 or Er:YAG laser — creates microscopic columns of controlled tissue injury in the scar, stimulating remodelling and new collagen production while leaving bridges of intact tissue for rapid healing. Particularly effective for textural improvement and softening of firm, irregular scars. Also effective for acne scars (atrophic type). Requires 2–4 sessions.
Non-ablative fractional laser — similar remodelling effect with less downtime; multiple sessions required compared to ablative.
Nd:YAG 1064nm laser — used for deeper scar treatment and in darker skin types where ablative lasers carry higher pigmentation risk.
In Indian patients, laser treatment must be approached with caution — the risk of post-inflammatory hyperpigmentation from any laser-induced injury is higher than in lighter skin. Lower energy settings, longer cooling intervals, and adequate skin preparation (depigmenting agents for several weeks before laser) reduce this risk significantly.
Surgical Scar Revision
Surgical scar revision physically excises the scar and re-closes the wound under optimised conditions — better wound closure, reduced tension, and appropriate suture technique. The result is a new scar, ideally better than the original.
When surgical revision is appropriate:
- Wide, stretched scars from wound closure under excessive tension — revision with undermining and closure in layers, with tension borne by the deep tissue rather than the skin, produces a narrower scar
- Scars crossing natural skin tension lines — repositioning the scar to align with relaxed skin tension lines (RSTLs) reduces visibility
- Irregular, step-off, or raised scar edges — direct excision and layered re-closure
- Very dark hyperpigmented scars in stable healed tissue — excision and re-closure with appropriate post-operative management
Surgical revision does not guarantee improvement — it is a planned trade of one scar for another, with expectation that the second scar will be better. This expectation must be realistic: the patient is not getting no scar, they are getting a better-positioned, better-healed scar.
Z-Plasty and W-Plasty
Z-plasty and W-plasty are geometric rearrangements of the scar tissue used to:
- Reorient a scar to align with relaxed skin tension lines (making it less visible)
- Lengthen a contracture scar (which is shortened by contraction)
- Break up a long linear scar into a less conspicuous irregular pattern
Z-plasty creates two triangular flaps that are transposed — the angle of the resulting scar changes, the length increases, and contractures are released. W-plasty converts a linear scar into a W-shaped pattern that blends with natural skin irregularities.
These techniques are appropriate for specific scar configurations and are not universally applicable. At Inform Clinic, the use of geometric scar revision techniques is decided individually based on scar length, location, and the specific improvement sought.
Post-Surgical Scar Prevention in Indian Patients
For patients undergoing surgery at Inform Clinic, the post-operative scar management protocol for patients at higher risk of abnormal scarring (those with previous hypertrophic or keloid scars, or high-risk anatomical sites) includes:
Wound closure technique — multilayer closure that removes tension from the skin surface, using deep absorbable sutures to bear tension. Fine sutures at the skin surface to minimise epithelial scarring.
Silicone gel from day 14 applied twice daily for 3–6 months.
Sun protection — broad spectrum SPF50 over all incision sites for 12 months. UV exposure in healing skin dramatically worsens pigmentation outcomes in Indian patients.
Intralesional TAC injection at the first post-operative review (4–6 weeks) if early hypertrophic changes are present — treating early, before the scar has consolidated, is significantly more effective than waiting until the scar is mature.
Scar massage from week 3 onwards — firm pressure over the scar for 5 minutes twice daily softens the scar by disrupting collagen fibres and reducing adhesion to underlying tissue.
Keloid Recurrence: Managing Expectations
The most important conversation to have before starting keloid treatment is about recurrence. Even with the best available treatment combination, keloids recur in a significant proportion of patients:
- Steroid injection alone: 50–70% recurrence rate
- Surgical excision alone: 70–100% recurrence rate (excision alone is contraindicated in keloids for this reason)
- Combined excision + immediate post-operative steroid injection + pressure: 20–40% recurrence
- Combined excision + post-operative radiotherapy (for resistant keloids): 10–20% recurrence
Post-operative radiotherapy (low-dose radiation to the keloid site after excision) is the most effective treatment for refractory keloids but requires collaboration with a radiation oncology department and carries the risks associated with targeted radiation. It is reserved for recurrent, refractory keloids that have failed other treatments.
Setting appropriate expectations — that keloid management is a long-term process requiring maintenance, not a single curative procedure — is fundamental to patient satisfaction.
Scar Treatment Cost in Hyderabad
Costs vary significantly based on scar size, type, treatment modality, and number of sessions required. Intralesional injections are significantly less costly per session than laser treatments. Surgical revision involves facility and anaesthesia fees. At Inform Clinic, a consultation with Dr. Dushyanth Kalva assesses the scar type, proposes the most appropriate treatment plan, and provides a clear session estimate and cost breakdown. For keloids specifically, a long-term management plan rather than a single-session quote is more informative about realistic total investment.
When to See a Specialist
The most common mistake patients make with problematic scars and keloids is waiting too long before seeking specialist treatment, or pursuing ineffective over-the-counter products for months before escalating to medical treatment.
Active hypertrophic scars respond significantly better to treatment in their first 6 months than after they have become established and firm. Keloids treated with silicone and steroid injection in their early growth phase are more responsive than established, hard keloids of several years duration.
If a scar is raised, itchy, growing, or causing you distress — do not wait a year to see if it improves on its own. At Inform Clinic in Hyderabad, Dr. Dushyanth Kalva's consultation for scars and keloids establishes the correct diagnosis, explains the range of appropriate treatments, and outlines realistic outcomes for your specific scar type and skin characteristics.
